Your rooftop solar is worth far more in your car than sold back to the grid. SundialEV automatically charges your EV from surplus solar instead of exporting it for pennies — set it once and forget it. Under "Net billing" electric plans (like NEM 3.0), utilities pay you a few cents for the solar you export, then charge you full price for the same energy at night. Sundial closes that gap: when your panels make more than your home needs, it sends the surplus to your car instead of the grid, saving most users on their electricity bills. • Set-and-forget — pick a charging floor and a battery reserve once; Sundial does the rest • Works with every Tesla model — and with any EV brand via an OCPP smart wall charger, like the Wallbox Pulsar Plus • Reads your production from Tesla, SolarEdge, Enphase solar systems (+ more now) • Coordinates with your Powerwall — you choose how full it gets before the car charges • Tops up on cheap off-peak power on your schedule, and avoids peak-rate windows when solar isn't available • Need range right now? One tap starts a full-speed charge — solar takes back over when it's done • No new hardware — works with the solar, battery, car, and charger you already own
